The Use of Adaptive Structures in Reducing Drag of Underwater Vehicles

Abstract

Experimental and theoretical studies by researchers in several countries over the last 30 years have shown that the generation of a traveling wave on the surface of a moving body may reduce drag. A laboratory-scale investigation using wave parameters identified in recent CFD studies will further understanding of the physics of traveling wave behavior. Requirements for an active wall test device are discussed in the light of previous experience and new developments in active materials and adaptive structures.
